Trans. wont kick in until the RPMs are uppretty high. After it kicks in its ok as long as the RPMs are up, but when they get lower it slips again.Fluid is not burnt and is very clean.Could the rpms give it added vacuum?
Transmission jerks on 1994 Mazda B3000
Check the transmission fluid level and smell it to see if it smells burned. The transmission has a removable oil pan perhaps get the oil hot drain it remove the pan and check fro debris and refill with fresh oil but it sounds like an internal transmission problem.
Could it be a vacuum problem?
